Description

Description: FIELD OF THE INVENTION The present invention relates to tape drives and, more particularly, to tape drives incorporating improved tapes.

[Prior art]

In order to eliminate the drawback of the conventional one-sheet type device in the multi-item information input device, that is, it takes too much time to call a desired item written on a sheet to a predetermined position, the inventor of the present invention has various advantages. Has developed a special tape drive device (for example, Japanese Patent Application Nos. 59-27842 and 59-27844). When these tape drives respond to a multi-item information input device (variable item keyboard), if you write many input items on each tape, you can change the input items instantly by moving a small amount of tape (page Since the change can be performed, a desired input item can be called to a predetermined position in a significantly shorter time than the conventional one-tape type information input device. Among these special tape drive devices, a tape drive device that enables both sides of the tape to be used simultaneously (Japanese Patent Application No. 59-
According to one application example of No. 27844), a pair of rollers (a first roller and a second roller) is wound from one end with one surface inside to the first roller and the other surface inside from the other end to the first roller. A plurality of sets of roller / tape assemblies consisting of a tape wound around two rollers are arranged in parallel or annularly, and these rollers are simultaneously driven to rotate to move all the tapes by the same amount at the same time.

However, when applied to a multi-item information input device, such a tape drive device needs to have a large number of memories or the like corresponding to the input items written on the tape in the input device, and thus the internal structure of the entire input device. In addition, the electrical system becomes relatively complicated.

An object of the present invention is to provide a tape drive device that solves the above-mentioned difficulties.

[Structure of Invention]

To achieve the above object, in the tape drive device of the present invention, one surface (front surface) of each tape is a surface on which information (for example, input items) can be written, that is, a visible display surface, and the other surface (back surface) of each tape is information. It is configured as a memorable magnetic surface.

〔Example〕

Referring to the drawings, an embodiment of the present invention will be described. The tape drive device 10 of the present invention shown in FIG. 1 is the specification of Japanese Patent Application No. 59-27844 and No. 59-27842 of the present inventor. An elongated first structure having a structure similar to that of the example of the tape drive disclosed in the specification and having a circular or regular polygonal cross section (regular pentagon in the example shown) extending parallel to each other as shown. A plurality of rollers 1 are juxtaposed substantially side by side on the same plane P, and an elongated second roller 2 having a circular or regular polygonal cross section (circular in the illustrated example) corresponding to each first roller is provided as the first roller 1.
The first roller 1 and the second roller 1
The roller 2 forms a pair of rollers. For each pair of rollers, the corresponding tape 3 is wound from one end to the first roller 1 with its one surface F inside, and from the other end of the tape to the second roller 2 with its other surface f inside. The rotation of these rollers 1 and 2 is carried out by a suitable known driving means, for example, as shown in FIGS. , 5 mesh with each other (Fig. 2), or the opposite end shaft 1a (or 2a)
The endless toothed belt 8 is suspended (Fig. 3) on the gear 6 having the same diameter fixed to the drive gear 7 and the drive gear 7 fixed to the shaft 7a of the reversible pulse motor (not shown) (Fig. 3). It is carried out in such a manner that all the tapes 3 are simultaneously moved in the same direction by the same amount by rotating each tape by one degree. In addition, 9 is a belt tension roller.

In the present invention, as shown in FIG. 4, each tape 3 comprises two layers of thin films or sheets 11 and 12. More specifically, the tape 3 has a slightly smaller width W than the length of the rollers 1 and 2, and has a first layer 11 including a surface f on which characters and symbols can be written and printed and a magnetic surface F capable of magnetic storage. Second layer including 12
It consists of and. Exaggeratedly shown in FIG. 5, each pair of rollers 1,
On the other hand, such a tape 3 is wound once or many times around the first roller 1 from one end so that its magnetic surface F is on the inside, and its writable surface f is on the inside. Then, the other end is wound around the second roller 2 a number of times or once. Therefore, the writable surface f is exposed to the outside around the first roller 1, and the magnetic surface F is exposed to the outside around the second roller 2. In such a configuration, the tape portion (area) A on one side surface of the first roller 1
Is a display area, and one side of the second roller 2, for example, the area B, or the tape area C supported by the tape supporting member 13 is a storage area corresponding to the area A, and a suitable magnetic head 14 (roller is provided in the vicinity thereof. 2 movably) along the longitudinal direction. Since the tape is very thin and the distance between the rollers 1 and 2 can be set to be constant, the area A can be accurately corresponded to the areas B and C. Therefore, in the tape drive of the present invention, a series of desired items are written or printed in the tape area A along the longitudinal direction of the roller 1, and the information corresponding to the tape area B or C is correspondingly magnetically written. To memorize.
In the case of the roller 1 having a regular pentagonal cross section shown in the figure, the roller 1 is rotated leftward or rightward by 72 ° (360 ° / 5) by 72 ° (360 ° / 5) to write a desired item on the writable surface f newly reaching the area A, and this is performed. The magnetic surface F newly reaching the area B or C corresponding to
The information corresponding to is stored. In this way, each tape 3 can include a large number of desired visible items and a large amount of corresponding information.

Briefly explaining the operation of the apparatus shown in FIG. 1-5, the desired item written on one of the tapes 3 is the display area A.
The rollers 3 are moved by rotating the rollers 1 and 2 by the driving means shown in FIGS. Then, by pressing the switch corresponding to the position of the desired item among the switches (not shown) provided in the device corresponding to each item position, the corresponding information on the magnetic surface F is read by the head 14 and the electric signal is read. In a known manner to the associated device.

In this case, the number of memories and addresses to be used is much smaller than that of the conventional one.

FIG. 6 shows a tape drive device 20 according to another embodiment in which the arrangement of rollers is different. In this drive, the same first rollers 21 as in the previous embodiment are located substantially parallel to each other along the first circle C ₁ at substantially equal intervals, and the second rollers 22 are concentric with the first circle. Located parallel to the first roller along the second circle C ₂ . The tape 23 wound around the first roller 21 from the one end with the magnetic surface F inside and wound around the second roller 22 from the other end with the writable surface f inside has the same structure as the tape 3 shown in FIG. It is wound around the first and second rollers 21 and 22 in the same manner as in FIG. 5 to write desired items and store information in the display area A, the storage area B or C. 24 is a magnetic head similar to the magnetic head 14, and 25 is a tape support member.
Simultaneous rotation of the rollers 21 and 22 of the apparatus shown in FIG. 6 may be performed by any known driving means. For example, although not shown, gears having the same diameter are fixed to the end shafts of the first roller and the second roller to mesh with each other, and the same diameters are provided on the end shafts on the opposite side of the first or second roller. The gear may be inscribed in the drive ring gear or the belt (externally inscribed), and the reversible pulse motor may reversibly rotate the ring gear and the like.

As described above, the tape drive device of the present invention is disclosed in the above-mentioned Japanese Patent Application No. 59-2784.
